RSF > Opel 3 Catalytic

Uniquely Designed Single Door

The Opel is our most popular fireplace. Part of the growing Opel family, the Opel 3C is a catalytic fireplace with an elegantly shaped single door.

The Opel’s catalyst burns off harmful emissions and increases efficiency when the fire is burning at low temperatures. You get less creosote and more heat from your fire at low to medium burn rates. As a result, less fuel goes up your chimney in the form of smoke.

The technology in the Opel is the result of over 30 years’ of experience in making high efficiency fireplaces. Popular Science Magazine recommended the Opel for its efficiency and emissions reduction. Our engineers have refined this technology over time, making the Opel what it is today.

This fireplace is certified for use with 7" ICC Model EXCEL chimney only.

Catalyst Care Tips:

- Burn natural wood only. Do not burn chemical chimney cleaners, chemically treated wood, driftwood, construction scrap or garbage in your unit.

- Purchase the optional Digital Temperature Display (FO-DTD) to monitor the temperature of your catalyst.

- Maintain a healthy catalyst temperature between 175°C (350°F) and 700°C (1300°F). Prolonged high or low temperatures may shorten the life of your Opel catalyst.

- Remove cooled ash from the face of the catalyst by brushing it gently with a soft bristle brush (e.g. paint brush). Vacuum use near the face of the catalyst to remove the remaining ash is permitted; however avoid direct contact with the catalyst unit.

- Limit cleaning to the visible face of the catalyst only. Attempting to clean the individual catalyst openings may do more harm than good. Scrapers or hard bristle brushes are never recommended.
